Updates on Value Based Care

By May 13, 2019 No Comments

In medicine, reimbursement drives change in practice patterns. Bundled payments from Medicare epitomize a heightened value of measurable outcomes. The Merit Based Incentive Payment System (MIPS) directs physicians to report outcomes. Based on these data, bundled payments to practices may be altered (1). Anesthesiologists are uniquely situated to help reduce cost, improve efficiency, deploy protocols for enhanced recovery, all while ensuring that patient safety does not fall by the wayside.

In healthcare economics, value is defined as quality divided by cost. The unique challenge of computing and comparing value lies in the subjective nature of quality. While variables like length of stay, mortality after 30 postoperative days, reoperation, and surgical site infections are measurable, attainable values, they fail to capture all aspects of care. Furthermore, billing departments and clinical administration are distinct entities, and only recently are collaborative efforts attempting to bridge this historical artifact. Moreover, physicians of earlier generations were raised in a “cost-blind” pedagogy. Medical schools and residency programs are now integrating economics and encouraging consideration of cost into anesthetic plans.

While increasing quality is desirable for patients and providers alike, this hurdle often comes with greater cost in the form of new technology, training personnel, and clinical uncertainties. Moreover, few novel strategies have shown improvement in the already exceptional safety margin associated with the delivery of anesthesia care. Instead, practices often focus on cost containment. Personnel comprise the majority share of OR operating costs for most institutions. French et al found that nearly 80% of OR cost was due to employee compensation. Thus, optimizing staffing ratios is an obvious source for improvement in some practices. However, some novel incentives have been developed. For instance, some practices link provider bonuses to lean usage of volatile anesthetics by encouraging lower gas flows (2). Providers should be familiar with emerging strategies for cost containment.

Pathways for the Enhanced Recovery After Surgery (ERAS™) have shown promise since their original implementation in colorectal surgery patients. These pathways stress the importance of early ambulation, neuraxial and regional anesthesia where appropriate, antiemetics, and decreased fasting times as a bundled package. These concepts have been similarly employed to other surgical populations, including thoracic, pelvic, urologic, spine, and breast surgeries (3). While the mechanism behind why ERAS™ pathways expedite recovery is not fully understood, their implementation has become widespread. The success of ERAS™ is due in part to a multidisciplinary effort to modulate the perioperative trajectory for a standard surgical encounter. Yet, Anesthesiologists and anesthesia providers should continue to treat each patient and condition with consideration and not blindly yield to pathways when extenuating circumstances arise.

Criticisms of value-based care arise when groups or practices are unfairly penalized for inevitable, uncontrollable complications. For instance, the acute kidney injury (AKI) rate after cardiothoracic surgery is roughly 30%. The multifactorial nature of AKI has been investigated in many prospective studies. Patient, anesthetic, and procedural factors likely contribute (4). However, inadequate control of blood glucose levels is a factor which is known to complicate cardiac surgery. The core measures upon which reimbursement is based will continue to drive improvements in anesthetic care for a multitude of patients.
